Hazel sells books online for $10.95 each. all of her 630 customers came from her facebook friends. how much did she make through facebook sales?

$6898.50

Step-by-step explanation:

Cost price of one book = $10.95

Question says 630  friends bought her books.

And asks for total sales she made.

So we multiply cost of one book with the number of customers , it will give us the total sales.

So

Total sales = $10.95 * 630 =  $6898.50

Total sales = $6898.50

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
